Trang 212.4.5 Changing the control logic
The input signals are set to sink logic (SINK) when shipped from thefactory
To change the control logic, the jumper connector above the controlterminal must be moved to the other position
To change to source logic, change the jumper connector in the sinklogic (SINK) position to source logic (SOURCE) position usingtweezers, a pair of long-nose pliers etc Change the jumperconnector position before switching power on
Note
Fully make sure that the front cover has been reinstalled securely
The capacity plate is placed on the front cover and the rating plate is on the inverter Since these plates have the same serial numbers, always reinstall the removed cover onto the original inverter.
The sink-source logic change-over jumper connector must be fitted in only one of those positions If it is fitted in both positions at the same time, the inverter may be damaged
Trang 22(1) Sink logic type and source logic type
In sink logic, a signal switches on when a current flows from the corresponding signal input terminal
Terminal SD is common to the contact input signals Terminal SE is common to the open collector output signals
In source logic, a signal switches on when a current flows into the corresponding signal input terminal

Trang 262.5 When using the brake resistor (MRS, MYS, FR-ABR)
It is recommended to configure a sequence, which shuts off power in the input side of the inverter by the external thermalrelay as shown below, to prevent overheat and burnout of the brake resistor (MRS, MYS) and high duty brake resistor (FR-ABR) in case the regenerative brake transistor is damaged (The brake resistor can not be connected to the 0.1K or 0.2K.)

Trang 272.6 Power-off and magnetic contactor (MC)
(1) Inverter input side magnetic contactor (MC)
On the inverter input side, it is recommended to provide an MC for the following purposes
(Refer to page 3 for selection.)
1) To release the inverter from the power supply when the inverter's protective function is activated or when the drive is notfunctioning (e.g emergency stop operation) When cycle operation or heavy-duty operation is performed with an optionalbrake resistor connected, overheat and burnout of the discharging resistor can be prevented if a regenerative braketransistor is damaged due to insufficient heat capacity of the discharging resistor and excess regenerative brake duty.2) To prevent any accident due to an automatic restart at restoration of power after an inverter stop made by a power failure3) The control power supply for inverter is always running and consumes a little power When stopping the inverter for anextended period of time, powering off the inverter will save power slightly
4) To separate the inverter from the power supply to ensure safe maintenance and inspection work
The inverter's input side MC is used for the above purpose, select class JEM1038-AC3 MC for the inverter input sidecurrent when making an emergency stop during normal operation
(2) Handling of inverter output side magnetic contactor
Switch the magnetic contactor between the inverter and motor only when both the inverter and motor are at a stop When themagnetic contactor is turned on while the inverter is operating, overcurrent protection of the inverter and such will activate.When an MC is provided for switching to the commercial power supply, for example, switch it on/off after the inverter andmotor have stopped
REMARKS
Since repeated inrush currents at power on will shorten the life of the converter circuit (switching life is about 1,000,000 times.),frequent starts and stops of the MC must be avoided Turn on/off the inverter start controlling terminals (STF, STR) to run/stop theinverter

Trang 282.7 Precautions for use of the inverter
The FR-E700 series is a highly reliable product, but incorrect peripheral circuit making or operation/handling method mayshorten the product life or damage the product
Before starting operation, always recheck the following items
(1) Use crimping terminals with insulation sleeve to wire the power supply and motor
(2) Application of power to the output terminals (U, V, W) of the inverter will damage the inverter Never perform such wiring.(3) After wiring, wire offcuts must not be left in the inverter
Wire offcuts can cause an alarm, failure or malfunction Always keep the inverter clean
When drilling mounting holes in an enclosure etc., take care not to allow chips and other foreign matter to enter theinverter
(4) Use cables of the size to make a voltage drop 2% maximum
If the wiring distance is long between the inverter and motor, a main circuit cable voltage drop will cause the motor torque
to decrease especially at the output of a low frequency
Refer to page 9 for the recommended wire sizes.
(5) The overall wiring length should be 500m maximum
Especially for long distance wiring, the fast-response current limit function may decrease or the equipment connected tothe secondary side may malfunction or become faulty under the influence of a charging current due to the stray capacity
of the wiring Therefore, note the overall wiring length (Refer to page 10)
(6) Electromagnetic wave interference
The input/output (main circuit) of the inverter includes high frequency components, which may interfere with thecommunication devices (such as AM radios) used near the inverter In this case, install the FR-BIF optional radio noisefilter (for use in the input side only) or FR-BSF01 or FR-BLF line noise filter to minimize interference
(7) Do not install a power factor correction capacitor, surge suppressor or radio noise filter on the inverter output side.This will cause the inverter to trip or the capacitor and surge suppressor to be damaged If any of the above devices areconnected, immediately remove them
(8) Before starting wiring or other work after the inverter is operated, wait for at least 10 minutes after the power supply hasbeen switched off, and check that there are no residual voltage using a tester or the like The capacitor is charged withhigh voltage for some time after power off and it is dangerous
(9) A short circuit or earth (ground) fault on the inverter output side may damage the inverter modules
Fully check the insulation resistance of the circuit prior to inverter operation since repeated short circuits caused byperipheral circuit inadequacy or an earth (ground) fault caused by wiring inadequacy or reduced motor insulationresistance may damage the inverter modules
Fully check the to-earth (ground) insulation and phase to phase insulation of the inverter output side before power-on.Especially for an old motor or use in hostile atmosphere, securely check the motor insulation resistance etc
(10) Do not use the inverter input side magnetic contactor to start/stop the inverter
Always use the start signal (turn on/off terminals STF, STR-SD) to start/stop the inverter (Refer to page 20)
(11) Across P/+ and PR terminals, connect only an external regenerative brake discharge resistor
Do not connect a mechanical brake
The brake resistor can not be connected to the 0.1K or 0.2K Leave terminals P/+ and PR open
Also, never short between these terminals
Trang 29(12) Do not apply a voltage higher than the permissible voltage to the inverter I/O signal circuits.
Application of a voltage higher than the permissible voltage to the inverter I/O signal circuits or opposite polarity maydamage the I/O devices Especially check the wiring to prevent the speed setting potentiometer from being connectedincorrectly to short terminals 10-5
(14) If the machine must not be restarted when power is restored after a power failure, provide a magnetic contactor in theinverter's input side and also make up a sequence which will not switch on the start signal
If the start signal (start switch) remains on after a power failure, the inverter will automatically restart as soon as thepower is restored
(15) Instructions for overload operation
When performing operation of frequent start/stop of the inverter, rise/fall in the temperature of the transistor element ofthe inverter will repeat due to a repeated flow of large current, shortening the life from thermal fatigue Since thermalfatigue is related to the amount of current, the life can be increased by reducing current at locked condition, startingcurrent, etc Decreasing current may increase the life However, decreasing current will result in insufficient torque andthe inverter may not start Therefore, choose the inverter which has enough allowance for current (up to 2 rank larger incapacity)
(16) Make sure that the specifications and rating match the system requirements
(13) Provide electrical and mechanical interlocks for MC1 and MC2
which are used for bypass operation When the wiring is
incorrect and if there is a bypass operation circuit as shown
right, the inverter will be damaged when the power supply is
connected to the inverter U, V, W terminals, due to arcs
generated at the time of switch-over or chattering caused by a
sequence error

Trang 302.8 Failsafe of the system which uses the inverter
When a fault occurs, the inverter trips to output an alarm However, an alarm output signal may not be output at an inverteralarm occurrence when the detection circuit or output circuit fails, etc Although Mitsubishi assures best quality products,provide an interlock which uses inverter status output signals to prevent accidents such as damage to machine when theinverter fails for some reason and at the same time consider the system configuration where failsafe from outside the inverter,without using the inverter, is enabled even if the inverter fails
(1) Interlock method which uses the inverter status output signals
By combining the inverter status output signals to provide an interlock as shown below, an inverter alarm can bedetected
(2) Backup method outside the inverter
Even if the interlock is provided by the inverter status signal, enough failsafe is not ensured depending on the failurestatus of the inverter iteself For example, even if the interlock is provided using the inverter alarm output signal, startsignal and RUN signal putput, there is a case where an alarm output signal is not output and RUN signal is kept outputeven if an inverter alarm occurs
Provide a speed detector to detect the motor speed and current detector to detect the motor current and consider thebackup system such as cheking up as below according to the level of importance of the system
1) Start signal and actual operation check
Check the motor running and motor current while the start signal is input to the inverter by comparing the start signal tothe inverter and detected speed of the speed detector or detected current of the current detector Note that the motorcurrent runs as the motor is running for the period until the motor stops since the inverter starts decelerating even if thestart signal turns off For the logic check, configure a sequence considering the inverter deceleration time In addition, it isrecommended to check the three-phase current when using the current detector
2) Command speed and actual operation check
Check if there is no gap between the actual speed and commanded speed by comparing the inverter speed commandand detected speed of the speed detector
